Pulse sensor for body pulse rate measuring means
Abstract
Abstract A measuring apparatus having a housing, an electric meter mounted therein and a temperature sensitive probe removably connected thereto and with an amplifier therein, and a source of electric power associated therewith to generate temperature responsive output signals which are received by the meter to thereby indicate the temperature of the body. A pulse sensitive element is connected to the housing, and the associated source of electric power, which generates pulse responsive output signals which are modified and fed to the meter for indicating the rate of the body''s pulse. The electric circuits between the power source, the sensors and he the meter are normally open and easily operated pushbutton switches are provided to temporarily close one or the other circuit when a reading on the meter is to be taken.
